Abstract(in English) | AlGaN/GaN HEMTs are attractive devices for high power switching applications because of their high electron mobility and high breakdown characteristics. But it is difficult to realize normally-off characteristics due to the high 2-DEG density. To solve the issue, we have developed AlGaN/GaN HEMTs with recessed gate structure. We obtained the HEMT with the threshold voltage of 0.3V, which means completely normally-off characteristics, and observed no significant on-state resistance increase. The on-state resistance of 2.0mΩcm^2 and the breakdown voltage of 400V were also obtained. The obtained on-state resistance is the lowest value of normally-off AlGaN/GaN HEMTs to our best knowledge. |
